Product details
Overview
TLV2332ID from Texas Instruments is a dual, low-voltage, medium-power operational amplifier in the LinCMOS™ family, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It delivers 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate at 3 V, with rail-to-rail output swing and input common-mode range extending to the negative rail - ideal for battery-powered sensor signal conditioning and portable instrumentation.
For engineers reviewing the TLV2332ID datasheet, TLV2332ID pinout, TLV2332ID application, or TLV2332ID equivalent, this page provides verified package mapping (SOIC-8), confirmed electrical specs (e.g., 9 mV max VIO, 310 µA max IDD per amp), real-world use cases in low-current analog front-ends, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TLV2332ID implements a dual-channel, internally compensated CMOS op-amp architecture using Texas Instruments' LinCMOS™ process, enabling ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance (10¹² Ω). Its input stage supports common-mode voltage down to the negative rail and up to VDD –1 V, while the output stage drives rail-to-rail under light loads.
It is fully characterized at both 3 V and 5 V supply voltages, with guaranteed performance over temperature (–40°C to 85°C). The device incorporates ESD protection (2000 V HBM), latch-up immunity, and operates with supply currents as low as 160 µA per amplifier at 25°C - balancing ac performance and microamp-level power efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables direct integration into 3 V and 5 V systems, including single-cell Li-ion and multi-cell alkaline battery rails. |
| Unity-Gain Bandwidth | 300 kHz at 3 V - sufficient for anti-aliasing, sensor amplification, and active filtering in sub-MHz signal chains. |
| Slew Rate | 0.38 V/µs at 3 V - supports clean amplification of low-frequency transients without distortion in portable medical or environmental sensors. |
| Input Offset Voltage | 9 mV max (–40°C to 85°C) - ensures stable dc-coupled gain accuracy in precision instrumentation front-ends. |
| Supply Current per Amplifier | 310 µA max over full temperature - enables multi-channel, always-on monitoring with minimal battery drain. |
| Input Bias Current | 0.6 pA typ at 25°C - preserves signal integrity when interfacing with high-impedance sources like pH electrodes or piezoelectric sensors. |
| Common-Mode Input Range | Extends to negative rail and up to VDD –1 V - simplifies single-supply design by eliminating level-shifting circuitry. |
Pinout & Package
TLV2332ID is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package (D package), surface-mount compatible with standard reflow profiles. Pin 4 is GND (VDD–), and Pin 8 is VDD (positive supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 (1OUT) | Provides buffered, rail-to-rail output signal; capable of sourcing/sinking ±30 mA. |
| 2 | Inverting Input of Amplifier 1 (1IN–) | Differential input node; high-impedance (10¹² Ω) interface for feedback networks or sensor bridges. |
| 3 | Non-Inverting Input of Amplifier 1 (1IN+) | Differential input node; accepts signals down to GND and up to VDD –1 V. |
| 4 | GND / VDD– | Reference return path for both amplifiers; must be low-impedance for noise control. |
| 5 | Non-Inverting Input of Amplifier 2 (2IN+) | Independent input for second channel; identical electrical behavior to Pin 3. |
| 6 | Inverting Input of Amplifier 2 (2IN–) | Independent input for second channel; identical electrical behavior to Pin 2. |
| 7 | Output of Amplifier 2 (2OUT) | Second independent rail-to-rail output; enables dual-path signal processing in compact layouts. |
| 8 | VDD | Positive supply rail; accepts 2–8 V; decoupling capacitor required near pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 150 mV of GND and within 190 mV of VDD at 1 mA load - maximizes dynamic range in low-voltage systems. |
| Input common-mode range includes GND | Accepts inputs from –0.2 V to VDD –1 V - eliminates need for external biasing in single-supply sensor interfaces. |
| Ultra-low input bias current | 0.6 pA typical at 25°C - prevents loading errors in high-Z applications such as photodiode transimpedance stages. |
| ESD protection (2000 V HBM) | Integrated protection per MIL-STD-883C Method 3015.2 - reduces need for external TVS in handheld or field-deployed equipment. |
| Stable at unity gain | Internally compensated for ≥100 kΩ load and ≤20 pF capacitance - simplifies layout with no external compensation required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Lower quiescent current (20 µA vs. 310 µA), but reduced bandwidth (130 kHz) and slew rate (0.12 V/µs). | Better suited for ultra-low-power sleep-mode sensing; less suitable for dynamic signal capture above 50 kHz. | Select TLV2372IDR only if average supply current <50 µA is mandatory and bandwidth requirements are ≤100 kHz. |
| LMV358IDR | Higher supply current (150 µA typ per amp), wider VDD range (2.7–5.5 V), no rail-to-rail input (common-mode limited to VDD –1.3 V). | Compatible with legacy 3.3 V digital rails; lacks true ground-sensing capability for direct sensor interfacing. | Choose LMV358IDR when interfacing with 3.3 V logic domains where input rail-to-rail is not required and cost is prioritized. |
Compared with TLV2332ID, TLV2372IDR trades ac performance for extreme power savings, while LMV358IDR offers broader vendor support but sacrifices input-range flexibility - TLV2332ID remains optimal for balanced low-voltage, rail-to-rail, and medium-bandwidth needs.

FAQ
What is the maximum operating temperature range for the TLV2332ID?
The TLV2332ID is rated for continuous operation from –40°C to +85°C ambient temperature. This industrial-grade range is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official SLOS189 datasheet, and applies to all electrical specifications unless otherwise noted.
Does the TLV2332ID support true rail-to-rail input operation?
The TLV2332ID supports rail-to-rail output swing but its input common-mode range extends to the negative rail (GND) and up to VDD –1 V - not full rail-to-rail input. At 3 V supply, VICR is specified from –0.2 V to 1.8 V; at 5 V, it is –0.2 V to 3.8 V. This allows ground-referenced inputs but excludes the positive rail itself.
Can the TLV2332ID drive capacitive loads directly?
The TLV2332ID is stable driving up to 20 pF with a 100 kΩ load, as verified in unity-gain configuration per Figure 36 of the datasheet. For larger capacitive loads (>50 pF), external isolation resistance (e.g., 100 Ω in series with output) is recommended to maintain phase margin >36° and prevent peaking or oscillation.
Is the TLV2332ID pin-compatible with other dual op-amps in SOIC-8 packages?
No - TLV2332ID uses a non-standard pinout: Pin 4 = GND, Pin 8 = VDD, with amplifier inputs/outputs arranged as 1OUT/1IN–/1IN+/GND/2IN+/2IN–/2OUT/VDD. It is not pin-compatible with industry-standard dual op-amps like LM358 or TL072, which place VDD on Pin 8 and GND on Pin 4 but assign different signal functions to Pins 1–7.
What is the typical input offset voltage drift over temperature for TLV2332ID?
The TLV2332ID has an average temperature coefficient of input offset voltage (αVIO) of 1 µV/°C (typ) from 25°C to 85°C, as specified in the Electrical Characteristics table. Over the full –40°C to 85°C range, total drift remains within ±1.7 µV/°C (max), contributing less than 0.25 mV of additional offset error across the operating range.
